To raise your Pokemon's affection as fast as possible, you need to:
-Feed your pokemon treats (which can be obtained from mini games) (5 the first time, then 3 each time afterwards)
-Pet/Rub/Molest/(whatever you want to call it) your Pokemon (5 the first time, then 3 each time afterwards)
-unlock unlimited mode of the 'Heads-Up' mini game then play it. Getting over 100 score is enough to get you through.

After you clear a round, feed your Pokemon and pet him/her afterwards. Affection is raised when your Pokemon gets hearts above his/her head. This is gained from feeding and petting him/her. Once you reach the limit for petting your Pokemon, he/she will get a music note above their head instead. This is an indication that you can not give the Pokemon any more affection until you play a mini game.

When feeding the Pokemon, you need to hold the food over his mouth or in front of his/her hand. Depends on how tall the Pokemon is. When the Pokemon is almost full, it will eat slower than it did with the previous treats. When it is, he/she'll look away. Drag the treat back to the icon to the top left unless you want to drop the food instead. Like petting, you can not feed it again until you play the mini game again.

Hope this helps. ^^

The best stats you can get for Yveltal are 201HP, 151Atk/Sp.A(give or take depending on nature), 119Spd(Give or take depending on nature) and 114(?)Def/SpD (once again, give or take depending on nature). The ideal ones you want to look out for are HP/Sp.A/Spd. Anything with a few points below make it still worth keeping. Just +/-10% for nature and if the stats are way lower than it should be then you'l know that the IVs are very low.

Pokemon Amie doesn't work in online battles otherwise it'd be even more broken. I hate to have the RNG Goddess screw me over as much as it does normally in online battles. ._.

I didn't use it on my Pokemon until the day after we fought. :goodtea:

No problem. I also wrote a bit more on Yveltal after just above.

Briefly stopping by...

Adding on to what AhGwee mentioned, if you raise the Pokemon's affection to MAX (five hearts) you will get more critical hits during your battles. (I don't know if you can get criticals outside of the game if you're playing with real players)

Also, this is the method to get Sylveon. Raise the affection to its maximum and teach it a Fairy move. Fullness and enjoyment don't need to be maxed.
